A CORPORATION OF NEW YORK WATER STERILIZIN G FILLING DEVICE Application filed June 17,

My invention relates to an improvement in a water sterilizing filling device and the will be more fully hereinafter pointed out.

ing tanks or positively in case of any leak in for convenience In sterilizing water for use in connection with operations and in hospitals it is imperative that not even the minutest drop of unsterile water should be added to the sterilized water.

Many have attempted to supply this great need in the furnishing of sterile water but this important problem has never been completely solved until the invention of my device.

My device furnishes a positive indicating means to the nurse or operator so that they know accurately whether water is being added to the sterilizing tank and furnishes positive means in a single control for directing said water to either of two sterilizshutting it oil and this single control valve positive means are furnished for effecting a complete drainage of said leaking Water so that it cannot reach either of the sterilizing tanks by accident.

Referring to the drawings, Figure 1 is a front elevation of my complete water filling control device, part being shown in section and being also broken away in the middle in illustration.

In the drawings 20 is a filter tank which has a nipple 21 at its lower end to which a Water inlet control valve body 22 is connected by means of an inlet pipe 23. The

connected to two liqupper portion of the tank 20 has an annular 4 is separated from the lower end of the filter member 25 by means of an annular flexible washer 29. On the upper end of the filter member 25 is a circular plate 30 having openings 31 cut therethrough and a flexible washer 32 is mounted between filter member 25 and plate 30. The plate 30 has a cylindrical tapered bearing member 34 which is integral with the plate 30 and the upper end of the rod 26 has a threaded portion 35 over which a locking screw 36 having a central connecting pipe 62 or 63 respectively and and the tapered end internally threaded portion adapted to engage the threaded portion 35 is adapted to be turned down by handle 38 so as to lock the plate 28, filter member 25, plate 30 together.

A casting comprising a cap member 37 is adapted to fit over the cast1ng2A with gasket 33 between and said cap 37 forms an internal water containing passage A0 and has an outlet passageAl leading therefrom into a larger outlet A2and said cap 37 has a tapered boring A3 at its upper end. A release screw 39 is adapted to be screwed down to break the connection between cap 37 and casting 2A.

A clamping ring AA is adapted to fit over said cap 37 and engage the casting 2A, being secured thereto in the usual well known manner by means of screw bolts A5. At the upper part of the clamping ring AA' s an internally threaded boring at A6 in which is adapted to be threaded a bolt A7 having a knurled handle A8 rigidly secured thereto A9 of said bolt A7 engaging the tapered boring A3 on the head of the cap 37 so as to lock the same. tightly in a water-tight manner over the washer plate A valve body 50 is connected by means of an externally threaded pipe connection at 51 to the outlet A2 and a spindle valve 52 is mounted in the body 50 by. means of spring 53 in the usual well known manner. The valve 52 has an annular cut out 5A near its upper end and an annular cut out 55 near its lower end and these two annular cut outs 5A and 55 are connected by cross cut out members56 which serve to catch any drop of water which may accidentally leak from said valve, and a waste drain 5 connects to said annular cut out 5A. The body 50 has an inlet passage 58 which connects to a passage 59 in the valve 52 and said pas- ,sage 59 may be connected by the turning of the valve 52 to connect either with the outlet 60 or 61 of the body 50 so as to pass into thence into sterilizing tanks 6A and 65- respectively. A semi-circular dial member 66 is rigidly secured to the body 50 by means of screws 67 in the usual manner, and a control cap 68 having a handle 69 is rigidly secured to the lower end of the valve 52 in the usual manner by means of a pin 70 which passes through the hole 71 in the lower end of the valve 52. The cap 68 also carries integral therewith an indicating pointer 72 which travels around'on the dial 66 so as to indicate the exact position of the valve 52 at all times and there are stop members 73 at the lower edge of either side of the dial 66 to limit the movement of the pointer 72- and the valve 52 controlled by the operation of the handle 69.

An inlet spindle valve 7A is mounted in the valve body 22'under constant spring tension of the spring 75 being held in said operative position by means of a dial plate 76 which is rigidly secured to thebody 22 by means of screws 77. A cap 78 to which is integrally secured a handle 79 and a pointer member 80 is mounted over the lower end of the spindle valve 7A being secured thereto by means of a pin which is not shown but which is the same as that shown at 70 in Figure 11 in connection with spindle valve 52. The valve 7A has a cut out portion or passageway 81 and the position of this cut out or passageway 81 permits the flow of the coming water through the inlet 82 and passage 83 to the inlet pipe 23 into the bottom of the filter body 20. The valve body 22 also has a drain outlet 8A. The passages 82, 83 and 8A are all internally threaded at their outer ends to receive the usual externally threaded pipe connection. It is to be particularly noted that the cut out por tion 81 or passageway in the spindle valve 7A is so constructed that it positively aligns and connects perfectly with either the water inlet 82 therethrough into the inlet 83 connecting with pipe 23 or connecting with 83 through the passageway 81 into the drain outlet 8A by the simple turning of the spindle valve 7A by means of handle 79 so that the pointer 80 rests on the indicating element inlet or on the indicating element drain.

In the operation of my device the operation of the handle 79 turning the pointer-80 to the inlet indicating means will turn the valve 7A so that the passageway 81 connects the inlet passage 82 with the passage 83 through pipe 23 into .the filter body 20 whence the water travelling through the openings 31 into the containing passage A0, thence through the outlet passages A1 and A2 into the pipe 51 throughthe spindle valve 52 through passage 59 and by turning the control handle 69 the pointer 72 may be turned to the indicating means Ofi or to Fill indicating means on either side of the indicating means whereby the water may be directed into either the passage 60 or 61 according to the position of the pointer 72.

If there is any leak in this valve 52 at any time either while filling one tank or when the valve is turned to OE and valve 22 is left open accidentally then the water will be collected either in the annular opening 5A or annular opening 55 and will pass through the connecting passages 56 to the annular opening 5A which always connects with the drain or waste 57, thereb positively preventing the admission 0% water through valve 52 by accident into either of the sterilizing tanks 6A or 65 at any time.

I claim:
